Lisa's score on the stats midterm was 90 points. the class average was 76 and the standard deviation was 77 points. what was her z-score?

as posted: 0.18182

more likely: 2.00

Step-by-step explanation:

z = (x -μ)/σ

... = (90 -76)/77 = 14/77 = 2/11

z ≈ 0.18182

We know that cutting and pasting often results in numbers being unintentionally repeated, so your 77 may be intended to be 7. In that case, the z-score is

... z = (90 -76)/7 = 14/7

z = 2
